Add a figure representing roles for co-instructors/helpers at pilot workshops

One section that I think could benefit from having an illustration to support it is the discussion of roles team members can take during a pilot workshop:

- instructor
- timekeeper
- notetaker(s)

Perhaps some cartoon depictions of people performing these roles?

Locate the curriculum section discussing roles during a pilot workshop and review how nearby figures or illustrations are organized. Create an illustration representing instructors, timekeepers, and notetakers, then confirm that it supports that section and matches the project's existing presentation style.
